I don’t know how old you are, I assume you’re an adult because you’re able to buy vapor liquids etc.

I would step in immediately. I’ve vaped for 5 years straight. It’s extremely addictive, way more than cigarettes. Mainly because the taste is really nice (whereas with cigarettes it’s nasty) and it’s much easier to hide because there is no smell.

I quit because I became pregnant, but just know how incredibly addictive it is and nicotine is horrible for once’s body, especially for someone who is that young. I think it’s your responsibility to do something with this knowledge and talk with your little bother about it beforehand.
